  26 DESCRIPTION
  27 -----------
  28
  29
  30 The :c:func:`hashkit_create()` function initializes a hashkit object for use. If
  31 you pass a NULL argument for hash, then the memory for the object is
  32 allocated. If you specify a pre-allocated piece of memory, that is
  33 initialized for use.
  34
  35 The :c:func:`hashkit_clone()` function initializes a hashkit object much like
  36 :c:func:`hashkit_create()`, but instead of using default settings it will use
  37 the settings of the ptr hashkit object.
  38
  39 The :c:func:`hashkit_free()` frees any resources being consumed by the hashkit
  40 objects that were initialized with :c:func:`hashkit_create()` or :c:func:`hashkit_clone()`.
  41
  42 The :c:func:`hashkit_is_allocated()` reports where the memory was allocated
  43 for a hashkit object.

  47 RETURN VALUE
  48 ------------
  49
  50
  51 :c:func:`hashkit_create()` and :c:func:`hashkit_clone()` will return NULL on
  52 failure or non-NULL on success.
  53
  54 :c:func:`hashkit_is_allocated()` returns true if the memory for the hashkit
  55 object was allocated inside of :c:func:`hashkit_create()` or
  56 :c:func:`hashkit_clone()`, otherwise it is false and was user-supplied memory.
